MOLUSCOS Y SU TAXOCENOSIS EN LOS FONDOS SOMEROS DEL SECTOR SUR DE LA PLATAFORMA CONTINENTAL DEL CARIBE COLOMBIANO
García-Valencia,Carolina; Díaz,Juan Manuel;
Boletín de Investigaciones Marinas y Costeras - INVEMAR , 2000,
Abstract: during a baseline survey of the shallow bottoms (10-50 m) of the southern continental shelf of the colombian caribbean, a total of 35 molluscan species belonging to 24 families was collected. three main molluscan bottom assemblages were recognized according to species composition and abundance, whose distribution seems likely to be controlled rather by depth than by sediment features. twenty four of the species were not recorded before from this area of the colombian caribbean.

Revista Colombiana de Psiquiatría , 2007,
Abstract: Objetivos: Describir en un grupo de sujetos que ingresaron por intento de suicidio a los servicios de urgencias de diferentes centros asistenciales de Medellín (Colombia), las características de aquéllos clasifi cados en la evaluación clínica psiquiátrica como de alto y bajo riesgo de reincidencia. Métodos: Estudio de corte transversal. Se hizo entrevista psiquiátrica a 238 individuos con intento de suicidio reciente para clasifi carlos en dos grupos, de alto y bajo riesgo de reincidencia, y se aplicó el instrumento de autorreporte “inventario de razones para vivir” (RFL). Posteriormente, se compararon las características de ambos grupos. Resultados: El 60,5% de los participantes se consideraron de alto riesgo de suicidio y los factores que se encontraron asociados fueron: trastorno depresivo mayor (OR=5,78, IC95%: 3,01-11,2), método violento (OR=5,21, IC95%: 1,89-14,37), intoxicación por sustancias psicoactivas durante el intento (OR=2,46, IC95%: 1,07-5,64) y puntuación en el “inventario de razones para vivir” (OR=0,47, IC95%: 0,34- 0,66). Conclusiones: Aunque los resultados no son generalizables, son similares a los encontrados en otros lugares. Es necesario hacer estudios longitudinales que permitan determinar la utilidad de estas características para predecir conductas suicidas. Objectives: To describe the characteristics that rendered subjects as having either high risk or low risk of suicide, according to the psychiatric evaluation performed after a suicidal attempt in different emergency services in Medellín, Colombia. Methods: It is a cross-sectional design. 238 individuals were interviewed to classify them in a group of high suicide risk or a group of low suicide risk. The self-report scale “Reasons for Living Inventory” (RFL) was applied. After that, characteristics of the high and low risk groups were compared. Results: The 60.5% of the participants were classifi ed as high risk attempters. The factors associated with high risk were: major depressive disorder (OR=5.78, CI 95%: 3.01-11.2), violent method (OR=5.21, CI 95%: 1.89-14.37), attempt during psychoactive substance intoxication (OR=2.46, CI95%: 1.07-5.64) and score of the “Reasons for Living Inventory” (OR=0.47, IC95%: 0.34-0.66). Conclusions: The results are similar to those reported in studies carried out in other places. Further longitudinal studies are required for determining the utility of these characteristics to predict future suicidal behavior.
DISTRIBUCIóN ESPACIAL, ABUNDANCIA Y RELACIóN CON CARACTERíSTICAS DEL HáBITAT DEL CARACOL PALA EUSTROMBUS GIGAS (LINNAEUS) (MOLLUSCA: STROMBIDAE) EN EL ARCHIPIéLAGO NUESTRA SE?ORA DEL ROSARIO, CARIBE COLOMBIANO

Boletín de Investigaciones Marinas y Costeras - INVEMAR , 2010,
Abstract: population density and spatial distribution of the caribbean conch, eustrombus gigas (linnaeus), as well as its association to different habitats were evaluated at 184 stations sampled systematically in two seasons (wet and dry) in nuestra se?ora del rosario archipelago. each individual was counted and measured in a circular area of 1256.6 m2 (sampling unit) by scuba diving and in situ observations on the types of habitats were made. the average density (±sd) of the species was low compared with other regions in the caribbean, 4.0 ind/ha ±10.8 and 3.7 ind/ha ±9.3, for the wet and dry seasons, respectively. adults represented 89 and 64 % of the population surveyed for each season, and were specifically located at bajo tortugas and isla tesoro. although reproductive activity was observed during the wet season, population density was below critical levels to guarantee the population's reproductive success. the spatial distribution analysis showed that the abundance of adults was spatially structured in both seasons, with important aggregations at bajo tortugas and isla tesoro. juveniles did not show spatial structure for neither season due to the low observed abundance. multiple regression models explained 48 and 14 % of the total variance in the abundance of adults during the wet and dry seasons, respectively; with depth, mean grain size, and percentage of mixed coral as predictor variables. it is recommended to establish bajo tortugas and isla tesoro as special protected areas in order to maintain the adult spawning stock, while the same conservation measure should be implemented at isla arena in order to protect juveniles on seagrass beds.
Eventos vitales adversos y suicidio: un estudio de autopsia psicológica en Medellín, Colombia Adverse Life Events and Suicide: A Case-Control Study of Psychological Autopsy in Medellin, Colombia

Revista Colombiana de Psiquiatría , 2008,
Abstract: Resumen Objetivo: Determinar si tipos específicos de eventos vitales constituyen de manera independiente factores de riesgo para el suicidio en Medellín, Colombia. Método: Estudio de casos y controles donde se tomaron 108 sujetos que fallecieron por suicidio (casos) y 108 que habían muerto por otras causas (controles). Se equiparó por edad y sexo. Tanto en casos como en controles se aplicó la autopsia psicológica y se recolectó información sobre eventos vitales adversos en los seis meses previos a la muerte. Resultados: Al ajustar por la presencia de trastornos psiquiátricos, intentos previos de suicidio y antecedentes familiares de suicidio en el análisis de regresión logística condicional, los eventos que mostraron ser factores que aumentan el riesgo de suicidio fueron: ruptura con la pareja afectiva, desempleo, y con un alto OR, pero sin ser estadísticamente significativo, dificultades económicas. Dada la imprecisión de los resultados, un análisis no condicional mostró que los eventos adversos asociados de manera independiente con suicidio fueron: ruptura con la pareja afectiva y dificultades económicas. Conclusiones: Los eventos vitales adversos ruptura con la pareja afectiva, difi- cultades económicas y desempleo aumentan el riesgo de suicidio, independientemente de la presencia de otros factores. Dichos eventos deben tenerse en cuenta tanto en el dise o de estrategias de prevención y en las políticas de salud mental. Objective: To determine whether specific types of adverse life events are risk factors for suicide in Medellin, Colombia. Method: This is a case-control study conducted among 108 individuals who committed suicide (cases) and 108 deceased from other causes (controls) matched by age and gender. Both cases and controls were examined through psychological autopsy and information about adverse life events during the previous six months was collected. Results: After adjusting for psychiatric disorders, previous suicide attempts and family history of suicide using a conditional logistic regression analysis, partnership dissolution, and unemployment were found to be risk factors for suicide. Additionally, financial difficulties showed a high OR although it was not statistically significant. Since results lacked precision, we fitted a non-conditional model which pointed to the following events as independent risk factors for suicide: partnership dissolution and separation, and financial difficulties. Conclusions: Partnership dissolution, unemployment, and financial difficulties increase risk of suicide, regardless of other factors. These adver

Abstract: El objetivo de este estudio es caracterizar clínicamente a los pacientes con trastorno afectivo bipolar I (TAB I), teniendo en cuenta la presencia de agregación familiar. Métodos: éste es un estudio observacional de corte transversal. Se extendieron genealogías de pacientes con TAB I, se identificaron familiares posibles afectados y psiquiatras que desconocían los antecedentes familiares de los sujetos realizaron una entrevista diagnóstica para estudios genéticos (DIGS) para confirmar el diagnóstico y recolectar información clínica. Se efectuó el análisis estadístico con el método de correspondencias múltiples. Resultados: se describen las características clínicas del TAB I en este grupo de pacientes. En el análisis de correspondencias se identificaron diversas agrupaciones sintomáticas. Se encontró asociación entre agregación familiar y mayor gravedad de los episodios depresivos junto con peor funcionamiento intercrítico. Conclusiones: (1) las características clínicas y agrupaciones sintomáticas encontradas son similares a las descritas en la literatura médica. (2) Los pacientes con agregación familiar parecen presentar un trastorno de mayor gravedad. (3) El análisis de correspondencias múltiples es una herramienta útil para estudios sobre fenomenología psiquiátrica. Objective: To clinically characterize patients with Bipolar Mood Disorder I (BD I), taking into account the presence or not of familial aggregation. Methods: This is an observational cross sectional study. The family trees of the patients with BD I were extended, possibly affected relatives were identified, and the Diagnostic Interview for Genetic Studies (DIGS) was performed by psychiatrists who did not know the family background of the subjects, in order to confirm the diagnosis and recollect clinical data. Results: The clinical characteristics of BD I were described in this group of patients. In the correspondence analysis various symptomatic groups were identified. An association between family aggregation and worse outcome of the depressive episodes, together with worse interepisode functioning was identified. Conclusions: (1) The clinical characteristics and symptomatic groups found are similar to those described in the literature. (2) Patients with family aggregation seem to have a worse outcome disorder. (3) Multiple correspondence analysis is a very useful tool for the study of psychiatric phenomenology.

Abstract: neuropsychology is the discipline that studies the mind-brain-behavior relationship through the analysis of the brain structure and brain processes supporting superior psychological functions such as consciousness, attention, learning, memory, thought, motivation and affection. neuropsychological disturbances on bipolar disorder patients have been poorly studied when compared to other psychiatric disorders like schizophrenia. however, increasing interest has developed due to it’s implications on the etiology, treatment, prevention, prognosis, adjustment predictors, social competence and quality of life of such patients. this article intends to review the research published relating bipolar disorder with neuropsychological abnormalities up to date. a review of research on different phases was done, including mania, depression or euthymia; comparative studies with schizophrenic patients and the likely influence of psychotropic medication are also discussed.
